NUT-LOCK.

Original application filed August 18, 1908, Serial No. 449,121. Dividedand this application filed February 13, 1909.

Patented June 29, 1909.

Serial No. 477,613.

T 0 all whom it may concern:

I Be it known that we, SAMUEL GINS, a subj eet of the King of Hungary,and WILLIAM PETERS, a citizen of the United States of America, residingat Monessen, in the county of l estmoreland and State of Pennsylvania,have invented certain new and useful Iniprovements in Nut-Locks, ofwhich the following is a specification, reference being had therein tothe accompanying drawing.

This invention relates to nut locks, and the subject-matter of thisapplication represents a division of our application for patent filedAugust 18th, 1908, patented Jan. 19th, 1909, N 0. 910,309.

The present invention has for its object to provide a nut lock of a moresimple and durable construction than the nut lock disclosed in thepatent above referred to. To this end, we provide a bolt withlongitudinal grooves and a nut With a recess for a plate having tonguesadapted to engage in the grooves of said bolt and prevent the nut fromrotating.

The invention will be hereinafter more fully described and thenspecifically pointed out in the appended claim.

Referring to the drawings :Figure 1 is a longitudinal sectional view ofour nut lock, Fig. 2 is an end view of the same, Fig. 3 is a perspectiveview of a detached locking plate, and Fig. 4 is a similar view of adetached nut.

In the accompanying drawings, 1 designates a bolt having the peripheryof the threaded end 2 thereof provided with longitudinal equally spacedgrooves 3, said grooves being approximately one-half the length of thebolt 1. Adapted to screw upon the threaded end 2 of the bolt 1 is a nut4 having the outer face thereof provided with a rectangular recess 5 andwith screw sockets 6. Detachably mounted in the recess 5 by screws 7entering the socket 6 is a rectangular plate 8 having screw openings 9.The plate 8 is provided with a central 0 ening 10 and with inwardlyprojecting equal y spaced lugs 11, said lugs being designed to engage inthe grooves 3 of the bolt 1, and prevent the nut 4 from rotating, whensaid nut is mounted upon the bolt 1 and the plate 8 within the recess 5.The lugs 11 are located on the nut at directly opposite the center ofthe four sides thereof. This arrangement throws the strain on said lugsout of line with the strain on the holding screws 7 which are located inthe corners of the recess. It will be ob served that after the nut 4 hasbeen screwed upon the bolt 1 that the plate 8 can be readily slippedupon the bolt into the recess 5 of the nut, and when secured therein bythe screws 7, the nut will be prevented from rotating upon the bolt.

We reserve the right to use our nut lock in connection with rail jointsand similar structures, and while in the drawings forming a part of thisapplication there is illustrated the preferred embodiments of ourinvention, we would have it understood that the detail constructionthereof can be varied or changed without departing from the spirit ofthe in vention.

Having now described our invention what we claim as new, is

In a nut look, a bolt having its threaded end formed with fourequally-spaced longitudinally-extending grooves square shaped in crosssection and a nut threaded on said end having its outer face formed witha recess, a locking plate adapted to lit snugly in the recess of the nuthaving a centrally-dis posed opening through which the threaded end olthe bolt is adapted to extend and four equally-spaced square shapedlocking lugs projecting toward the center of the opening andlocated onsaid plate at points diagonally cutting the axis of the corners of saidplate and screws extending through the corners of the plate into the nutso as to hold the plate in the recess and the locking lugs in thegrooves of the bolt.

In testimony whereof we itillX our signatures in the presence of twowitnesses.
